Secondary succession is one of the two types of ecological succession of plant life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.
Simply put, secondary succession is the succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession as:
Many mechanisms can trigger succession of the second including facilitation such as trophic interaction, initial composition, and competition-colonization trade-offs. The factors that control the increase in abundance of a species during succession may be determined mainly by seed production and dispersal, micro climate; landscape structure (habitat patch size and distance to outside seed sources); Bulk density, pH, soil texture (sand and clay).
Ecological Succession occurs when an ecosystem has a disturbance and must regrow. Succession is all about change.
There are two main types of succession, primary and secondary.
Primary occurs when an area has been almost destroyed and little life or soil remains.
Pioneer species are the first plants to regrow.
Secondary succession occurs where you have a disturbance but the soil remains.

Ecological Succession | Primary & Secondary
Ecological succession is how the makeup of a community changes over time, starting right after a disturbance. We can tend to think of succession as taking a really long time, and some types DO take a really long time, but sometimes it may only take a season or two. The most important thing to learn is that succession is all about CHANGE!

Mature forests contain a variety of plants. Prehistoric pines, old oaks and historical hickories dominate the area. Sometimes entire forests can be wiped out by natural disturbances like fire. The day after a fire the forest would look abandoned. However over time the forest would grow back. First low growing grasses would sprout. Then bushes followed by small trees. The predictable changes that occur in a community is called succession.
There are two kinds of succession. Primary succession is the changes that occur in an area where no soil existed. Ice melting to expose bare rock will go through primary succession. Over time, pioneer species will populate the area. Organisms like mosses and lichens break up the rock and help create soil. Next, seed dispersal will bring seeds to the new soil and small plants will start to grow. Over time the once bare rock will be a mature forest.
Secondary succession occurs when a developed ecosystem gets disturbed by natural disasters. Fires and tornadoes can wipe out fully developed pieces of land. Human activities like farming and logging can also change landscapes. First low growing plants will populate the area. Then trees appear and develop. Secondary succession creates a mature forest faster than primary succession because soil was already in the area.
Primary succession is growth for the first time. Secondary succession occurs where soil already exists. Both types of succession are a series of predictable changes in the development of an ecosystem.

Secondary succession is one of the two types of ecological succession of plant life. As opposed to the first, primary succession, secondary succession is a process started by an event (e.g. forest fire, harvesting, hurricane) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.
Simply put, secondary succession is the succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession as:
Many mechanisms can trigger succession of the second including facilitation such as trophic interaction, initial composition, and competition-colonization trade-offs. The factors that control the increase in abundance of a species during succession may be determined mainly by seed production and dispersal, micro climate; landscape structure (habitat patch size and distance to outside seed sources); Bulk density, pH, soil texture (sand and clay).
